The Truth about Violence

As a teenager, I once had an opportunity to fly in a police helicopter over a major American city. Naively, I thought the experience might be uneventful. Perhaps there would be no crime between 8:00 and 10:00 p.m. on a Saturday night. However, from the moment we were airborne, there was a fresh emergency every fifteen seconds: Shots fired… rape in progress… victim stabbed…It was a deluge. Of course, the impression this left on me was, in part, the result of a sampling bias: I was hearing nothing but incident reports from a city of 4 million people, most of whom would never encounter violence directly. (No one calls the police to say “Everything is still okay!”) Yet it was uncanny to discover the chaos that lurked at the margins of my daily routine. A few minutes from where I might otherwise have been eating dinner, rapes, robberies, and murders were in progress.
